I work for a company that sells an application for sending SMS through a GSM modem. The software was originally developed a couple of years ago by a 3rd party company which is no longer around. Recently we have had reports of duplicate messages being received. sometimes 2,3,4,5 times I have run tests on software and the AT command to send an SMS only happens once per message but every now and then multiple SMS are being received. The SMS are being sent by our software using AT commands and a GSM modem to mobile phones. Can anyone shed any light on what might be happening ??? or areas in which i should be testing ??? thanks for your help / advice | |||
